Title: Improvements in or relating to aircraft
IPC: B64C13/00
Filed: 1939-07-21
Abstract: 531,411. Controlling aircraft. TAMPIER, R. July 21, 1939, No. 21189. Convention date, Aug. 3, 1938. [Class 4] A movable control surface on an aircraft having fixed wings is operated by a motordriven rotating transmission connected to the movable surface by a device which converts the rotary movement into a rocking movement, reduction gearing being disposed adjacent the control surface. As described, aileron sections 1, 2 some of which are actuated by irreversible hinge mechanism 6 and others by reversible mechanism are operated from a continuously rotating internal combustion engine 9 through reversing gear and a clutch 54, 55. Alternatively, a reversible electro-motor may be used without a clutch and mechanical reversing gear. The motor 9 drives two oppositely rotating bevel wheels 43, 44 either of which may be clutched to a hollow shaft 45 upon movement of a lever 49 connected by a rod 51 and other rods and levers to a pilot's control. A cardan shaft 10, with joints at intervals, is connected to the devices 6 either by the bevel gears shown or by worm gear, each device 6 comprising a screwed shaft adapted to traverse a nut connected to a lever on a transverse shaft which actuates arms 24 secured to the aileron section 1. When the lever 49 is central, a cam 76 acting on a lever 74 ensures the disconnection of a clutch member 55, keyed to the shaft 10 from a clutch member 54 on the hollow shaft 45, but when either gear is engaged, a spring 56 causes engagement of the clutch members 54, 55. Pinions 61 on the. actuating shafts of the members 6 engage racks 60 on a rod 13 which is connected to a similar rod on the other side of the aircraft and to a manual control. The end of the rod is linked to a lever 29 which actuates a reversible hinge connected to the aileron section 2. A member 63 on the rod 13 ensures disengagement of the clutch 54, 55 at the limits of adjustment by displacing one or other of the levers 64, 65. Alternatively a nut traversed along the shaft 10 may be used for this purpose. The end of the lever 49, by engaging levers 81, 82 controls the throttle of the engine 9, the clutch actuated by the lever 49 having a long travel after engagement to enable the speed of movement of the ailerons to be controlled. The manual and power controls are operated by two hand wheels on concentric shafts.
Patent GB-276006-A (GB)
Title: Power steering for motor vehicles and self-propelled machines
IPC: B62D5/10
Filed: 1927-08-11
Abstract: 276,006. Servo-Frein Dewandre Soc. Anon. Aug. 14, 1926, [Convention date]. Hydraulic and pneumatic transmission.-Comprises suction-operated servo-motor steering-gear in which the steering hand-wheel controls a compound lever, one end of which actuates a distributor controlling a suction conduit by which a vacuum effect is exerted on a piston constituting the power element, the other end of the compound lever being under the control of a member which transmits the effort of the power element to the steering road wheels and also to the said lever, in such a way that the distributor is adjusted to the neutral position after the desired steering- movement has occurred. The steering handwheel operates the usual steering arm 20 which can move between stops 25, 26 and springs 28 before imparting motion to the rod 27 controlling the stub-axles. A two-armed lever 18 is pivoted at 19 on the arm 20, its upper end being connected by a link 21 to a distributing valve. 17 and its lower end is connected by a link 24 to the steering-rod 27. The valve 17 is adapted to put cylinders 6, 7 into communication either with the induction pipe 1 or with the atmosphere through a pipe 13. Pistons 8, 9 in the cylinders are connected by rods or cables 10, 11 to the rod 27. When the arm 20 is moved by the steering handwheel it moves relatively to the rod 27 compressing one of the springs 28, and the lever 18 is oscillated about its lower end so that the valve 17 is operated to put one cylinder in communication with the induction pipe and the other in communication with the atmosphere... The pistons 8, 9 are thereby operated and move the rod 27 until the return movement of the lever 18 caused thereby brings the valve 17 to its normal or central position. The movement of the valve may be damped by an hydraulic or other friction damper. The pipe 13 communicates with the upper part of the engine crank-case so that cily air is admitted to the cylinders 6, 7 and lubricates the parts. The Specification as open to inspection under Sect. 91 (3) (a) states that compressed liquid or fluid, e.g., cylinder gases, may be used to operate the power element. This subject-matter does not appear in the Specification as accepted.

Abstract: 188,099. Gill, H. A., (Multiplex Packeting & Filling Machine Co., Ltd.). Aug. 16, 1921. Fixed-chamber apparatus for granular and pulverulent materials ; varying quantity measured in.-In apparatus adapted for granular and pulverulent materials the measuring chambers are mounted in two groups, one above the. other, with valves between each upper and lower chamber, interconnected inlet and outlet valves, and means whereby the capacity of each pair may be varied within wide limits. An agitating device and means for facilitating flow are also described. A hopper 20 has passages 21 leading to the inlet valve 35 of the upper set of measuring chamber 48, the lower ends of the valves being flanged at 45 and slidable within the chambers. Both hopper and valves are fixed to a table 23 which is supported on jack-screws 24 working through fixed trapped bosses 25 and geared to a handwheel 30 which may be turned to lower the flanges into the measuring chambers. Each valve 35 has a crank-arm 36 pivotally connected through a bar 41 to a pivoted lever 43 provided with a slot 44 to allow of vertical adjustment of the bar. The chambers 48 have valves 53 at their lower ends and are mounted on a fixed table 27; these valves are piovided with crank arms 54 pivoted to a bar 55 having a hand-grip 150, and with flanges 56 slidable within the lower measuring chambers 57 which are mounted on a vertically movable table 64 operated by a hand-wheel 76, and have outlet valves 65. Bv raising the lower set of measuring vessels until the conical portions reach the flanges 56, and if necessary fitting displacing members within the vessels, the smallest measured volume is obtained. and any volume up to the combined capacity of each pair is obtainable. When using the bottom chambers only the upper ones are used as supply reservoirs, the valves 35, 65 being opened simultaneously while valve 53 is closed, and when using both sets the valve 53 is continually open. For facilitating the flow of flour &c. a breaker is arranged in the hopper, Fig. 6 comprising revoluble spokes 91 passing through slots 90 in a false bottom 89, and the diameter of the measuring vessels and valves increases progressively from the hopper to the outlet, also one side of the hopper may be made vertical.

[Also in Division G1] The dimension of an object, e.g. the thickness of a fibre issuing from a spinneret, is measured photo-electrically using the optical system shown. This comprises a source and condenser 1, 2, a Toepler optical system 3-6 provided with a collimating section 4, 5 in which the object is placed, an objective 11 and means for visual (13) and photo-electric (14) detection.
